behavior therapy a therapeutic approach in which the focus is on the patient's observable behavior, rather than on conflicts and unconscious processes presumed to underlie his maladaptive behavior.
Asexual reproduction is more common in invertebrate animals than in vertebrate animals. Unicellular and multicellular plants can reproduce both asexually and sexually. Common types of asexual reproduction include binary fission, budding, sporulation, regeneration, and vegetative propagation. 2 BINARY FISSION. Binary fission is the simplest type of asexual reproduction. During binary fission, a one.celled organism divides by mitosis to form two daughter cells of equal size. Both the nucleus and the cytoplasm divide equally.
